Application filed April 8, 1907.- Serial No. 366,989.

To all 'whom it may concern.'

Be' it known that we, PETER W. FULFORD and CHARLES STECHER, citizens of the United States, and both residents of Chicago, Cook county, Illinois, have invented new and useful Improvements in Pail-Earing Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in mechanisms for applying ears to pails, and has special reference to improvements in machines for double seaming or otherwise fastening ears in and upon lard pails and the like.

The object of our invention is to provide a machine of the class mentioned which shall quickly and accurately secure the ears upon metal pails of the kind referred to.

A further and particular object of our invention is to provide a single automatic machine which shall perform all of the operations of punching and flanging a pail, and of applying and fixing previously prepared' ears thereon.

Our invention consists in pail holding means, in combination with a pair of punching and flanging dies to operate, on a pail held by said means, ear-feeding means, a pair of ear clenching, seaming, or fastening dies for securing an ear in or upon the pail and means for operating said pairs of dies successively-- Our invention also consists in the combination of a set of dies adapted to punch holes in the opposite sides of a pail, with another set of dies adapted to fix ears in said holes, and means for feeding a pail; first, to the punching dies, and then to the ear affixing dies, and for thereafter removing the pail from the paths of said dies.

Our invention includes the combination of the aforesaid earing mechanisms proper with means for automatically feeding previously formed ears thereto.

More particularly, our invention comprises a pair of coacting punching dies for punching the side of a pail and forming a flange around each hole thus made; a pair of coacting finishing dies for inserting the ears in the holes formed by said punching dies and fastening the ears therein, and means for presenting a pail to said dies successively.

Our invention also comprises two sets of punching and caring dies, as mentioned, each set mounted upon a sli and adjustable toward or from each other to accommodate pails of various sizes.

Our invention further consists in the relatively adjustable punching and caring mechanisms mentioned,

f in combination with an automatic ear-feeding device for each and means for operating multaneously.

Our invention further consists in novel details of consaid mechanisms sistruction and in arrangements and combinations of parts; all as hereinafter fully described and particularly pointed outin certain of the claims. l

Our invention will be more readily understood by reference to the accompanying drawings forming parts of this specification.

Figure I is a front elevation of a pail caring mechanism embodying 'our invention, one 'side thereof being shown in section; Fig. II is a top plan view of the mechanism illustrated in Fig. I 5 Fig. III is a ci'oss seetion on the line X-X of Fig. I; Fig. IV is a detail View (upon an enlarged scale) of the ear feeding mechanisms; Fig. V is a detail sectional view (upon an enlarged scale) of the dies, illustrating the operation of the punching and langing dies; Fig. VI is a view similar to Fig. V illustrating the operation of the finishing dies, the same being shown almost closed; Fig. VII is a cross section upon the line Y-Y of Fig. I, the same being Shown upon an enlarged scale; Fig. VIII is a detail end view of a die holding block; Fig. IX is a detail sectional view of a portion of the side of a pail with the ear secured thereto; and Fi'g. X is a similar view of the ear before being secured to the pail.

As here shown in its preferred form our invention Consists in a machine adapted to apply previously prepared ears to lard pails and the like. It is adapted to operate automatically when once freed and set into motion by its driving clutch, and it is readily ladjustvable to different sizes of pails. As will be better understood later, our machine is adapted to apply different kinds of ears to pails of the class mentioned, provided the necessary changes are made in the dies, which latter are in every case conformed to the particular kind of ear, which is preferred by the user or purchaser of the pails. The principal parts or elements of our machine are, first, two pairs of coacting punching and Hanging dies adapted to perforate and Hang-e the sides of aV pail, preparatory to the reception of ears;-secoi1d, two pairs of coacting ear alixing lo" fastening dies, preferably arranged beneath the first mentioned dies; third, means for actuating the punching andl ear affixing dies successively; fourth, two ear feeding mechanisms which coact with the ear aiiiXing diesfand fifth, suitable means for feeding a paill to said dies in succession; the operation being such that the sides of the pail are first punched and flanged and 4then the ears are placed in the holes of the pail and are there fastened, after which the eared pail is removed or expelled to make place for another pail.

One pair of punching dies and one pair of earing or ear aflixing dies are preferably placed in one frame or carrier and the other pair are placed in another frame or carrier. These frames, or carriers, are adjustable upon the main frame of the machine, and it will be readily seen that in this way we-adapt the machine for use with. pails of different sizes. As a means of operating the die members which are in substantial abutment at the meeting ends of the two frames, or carriers, we preferably employ a single vertically movable operating member which is common to all said members. This part is arranged to first actuate the punching die members, and then the earing die members. The outer members of the dies are operated by cams that are suitably mounted upon respective frames or carriers. The ear feeding devices are preferably mounted upon respective carriers, likewise the means for operating certain members thereof. This arrangement of parts permits all of the moving .members to be driven from a single power shaft. This shaft, as well shown in Fig. I, is in gear connection with the die operating cams referred to, and the shaft itself carries a large cam which operates the single member employed in connection with the inner members of the pairs of dies. The cam on .said shaft performs a further office of operating the pail chuck, or carrier, being adapted to the necessary two stage downward movement of said chuck, by which the pail is fed to the punching and ear aixing dies in succession. The ears are held in magazines which constitute parts of the ear feeding mechanisms, and are released from their magazines one at a time by a simple mechanism which is preferably actuated from the reciprocating pail chuck. The driving mechanism is such as to be thrown into operation by aitreadle and is released automatically at the completion of a single cycle of movements, in other words, at the moment when the pail chuck returns to its normal, or receiving position. As will be better explained hereinafter the ears are fed upward to the earing dies at the instant that the pail descends, and the pail at such time provides or forms walls or guides which aid in retaining the ears and in leading them into proper positions in the pail and between the dies. In the machine illustrated, the ears are applied to the inner side of the pail and are thrust outwardly through the openings therein, to be seamed into place by the dies. In other words7 the ears are of a kind that require handling in this way, and hence, in being inserted are moved upwardly'within the pail. But it should be understood that our invention is not limited to the structures which are used in thus feeding the ears, as pail ears of some other kinds are applied from the outside of the pail and slight mechanical changes in the machine shown are sufficient TGa'dapt it to such usage. The modication required in this regard is so obvious that we have not deemed it necessary to illustrate the modified structure. These statements apply also with reference to the faces or configurations of the coacting dies, which, as before stated, necessarily take their shapes from the kinds or styles of ears to be used. `To avoid confusion and misunderstanding it is explained that in the particular machine herein shown it is necessary to substitute other chuck plates or parts when the machine is adjusted for a different sized pail, and likewise, the common actuating member of the inner dies is replaced by another of greater or less width, according as the carriers, or frames, are moved apart or more nearly brought together. a

Referring now to the drawings for a thorough understanding of the details of construction, it will be seen that the main frame or bed, A, of the machine is supported on legs, B, and is provided with ways, C, in or on its top. These ways extend from end to end ofthe frame or bed and in them we arrange the two die carriers or frames, D, D. These occupy reverse positions, in other words the dies are arranged in the adjoining or adjacent ends of the frames, D, providing a group of dies substantially at the center or vertical axis of the main frame. For adjusting the frames, D, D, we employ screws, cl, and after being adjusted they are fas-Y tened in place upon the ways by means of clamping blocks, d, provided on the main frame, A.. r1`he main frame is provided with a vertical bearing, 21, coincident with the vertical axis of the machine to receive the single or common actuating member of the dies, before alluded to. The die frames or carriers, D, D, are adjusted with relation to the bearing, 21, and the degree of separation thereof is determined by the diameter of the pail to be operated upon.

The carriers, D, D, are identical in construction, and this is true also of the parts carried thereby. A detailed description of one will serve for both, It will be noted that the dies are arranged at slight inclination upon carriers, D, when tapered pails are to be eared, but this is modified in the case of machines adapted to the earing of cylindrical pails, in which case the die members operate upon lines which are parallel with the top of the main frame. In either case the frame is provided with upright sides, 9, equipped with guiding ribs or gibs, 10, and is also provided with a bracket portion or standard, 1, at its inner end, the latter part containing the inner members of the dies. two slides held by the guide ribs, 10, and movable toward and from the blocks or standard, l.. The slides contain anti-friction rollers, 15. and 16 in their outer ends and are operated by cams, 17 and 1S, the latter fixed upon a vertical'shaft, H.

Referring to.Figs. 1, 2 and 7, it will be noted that pins, 7/ and 8, extend from the slides 7 and 8 through slots in the sides of the carrier, D. To these pins we attach the retracting springs, 7*L and 8*, which hold the slides back against the respective cams 1.7 and 18. The inner end of each slide, 7, 8, is equipped with a block, 11, having a separable clamping portion, 11. These blocks are threaded and contain the dies, 12 and 13, respectively, having threaded shanks which are adjustable in the blocks, 11. After being thus adjusted the dies are fastened or clamped by means of the parts, 114 It should be noted that the upper or punching die member, 12, is hollow, and that the inner end, 7/, of the slide, 7, is likewise hollow, affording a tube or passage through which the blanksor waste cut from the pails are discharged. The blanks fall from the passage, 7/, through holes, 7, 8, and Df, provided in the slides 7 and 8, and the carriers, D', as well shown in Fig. 1, clogging of the machine being thereby avoided.

A gap or opening is left between the outer dies and the bracket or standard, 1, to receive the side of a pail. The inner die members 2 and 3 are arranged in the bracket 1, having bearings therefor in alinement with the outer die members. The face or end of the die member, 2, properly conforms to the face of the die member, 12, the two together being adapted to punch an opening in the side of the pail and thereafter flange the metal around the opening, as well shown in Fig. 5.

7 and 8 are The die member, 3, likewise conforms to the outer member 13, the two dies being adapted to co-act in the insertion and clenching of an ear, 50, in the flanged opening of the pail, as well shown in Fig. G.

The die members 2 and 3 are provided with beveled ends, 2 and 3f, that engage the double wedge block or device, 19, which latter is the single operating member hereinbefore referred to. Upon the upward stroke of this member it engages the upper die member, 2, and drives the same outwardly toward the die, 12, and upon the downward stroke of the common actuating member, 19, the die 3, .is driven outward tolmeet the complementary member, 13.

The lower outer face of the bracket lis provided with a recess, 3, which communicates with the cylindrical opening that contains the die member, 3. The die member, when retracted, leaves space in the end of the bearing to receive an ear, 50. In the part, D, directly beneath the recess referred to is a pocket, 30, to hold an ear, 50, preparatory to the feeding thereof to the dies. Above the pocket, 30, is an upright spring or small bracket, 45, between which and the bracket 1, the ear is guided when raised to the ear affixing or seaming dies, 3-13.

The ears are supplied to the pocket, 1, by an ear feeding mechanism, P. This mechanism comprises the magazine, P, and the more steeply inclined discharge end or spout portion P thereof, together with an escapement device which is operated from the pail chuck, as more fully described hereinafter. The tube or chute, P, is attached to the carrier, D, and moves therewith. At its lower end it communicates with a .cross slot, 3W, through which the ears pass to the pocket, 30.

For lifting the ears into position between the dies, 3 and 13, we employ a plunger, 40, arranged in guides 41, on the lower part of the casting or frame, D. This slide is actuated by a lever, J, pivoted on the frame D, and operated by a cam, 14, on the shaft H, the latter engaging an antifriction roll, 43, on the end of the lever, .l

As a convenient means of supporting the shaft, H, we provide the frame D, with the depending bracket, E, and arrange the shaft bearings, H and H in the parts D and E. The bracket, E, also has a horizontal bearing, F/, for the main power shaft, F, and as shown in Fig. 1, said power shaft is connected with the shaft H, by bevel gears, l-l The gear, If, is slidably fixed on the shaft, F, and hence shaft, H, remains in connection with the shaft, F, when thc member, D is moved or adjusted on the main frame.

The end of the shaft, F, extends through a bearing in or on the main frame and by means of collars is fixed against longitudinal movement in the main frame. 'This is desirable and practically necessary as the shaft carries the cam, L, which operates the central mechanisms of the machine and it must needs maintain its position in the plane of the central vertical axis of said mechanisms, as more fully explained hereinafter.

As best shown in Figs. 1, 2, 5 and 6, the two carriers D,

with their complements of dies and operating members are placed end to end in such manner that the inner dies thereof stand very close together, with only a small space between them. As little movement of the frames, D, is required in the adjustments from large to small pails, or from small to larger sizes we find it possible to retract the members 2-2, and the members 3-3, by springs, 6, which extend between and join respective pairs thereof. The members 2 and 3 are provided with cross pins, 4; these extend through slots, 5, in the brackets, 1, and are joined by said springs (i. The slots limit the retractive movement of the members by the springs, and the pins prevent the turning of the die members in the brackets or blocks, 1-1.

20 is a vertical connecting rod or plunger arranged in the fixed bearing 2l., and having a cross slot in its top wherein the lower end of the member 19, is secured by a pivot pin, 20/. The lower end 19/ of the member, 19, is rounded and loosely fits within the plunger, 20, so that it may swing or yield slightly at its upper end, as sometimes required, to follow the die members 2 and 3, when the frames or carriers are carelessly adjusted. 'The upper end of the member, 19, is provided with beveled shoulders, 19a, to engage and drive apart the die members, 2-2, and is provided with straight shoulders, or edges, 19", to drive between said members, 2, and positively h old them apart in the manner shown in Fig. 5,

t. e. at the instants that they receive the pressure of the outer die members, 12-12. In like manner the lower part of the member 19 is provided with beveled shoulders, 190, terminating in straight or flat portions, 191, operative to project the two members 3-3, and lock them momentarily, to receive the pressure of the opposed dies 13-13 The member 19 is operated by means of the cam L on the shaft F, said cam being provided with a groove, M, which contains the roller 22 on the lower end of the plunger` 20. As best shown in Fig. 3 the groove has portions, m, and mf, for forcing the member to the extreme ripper position and for drawing it down to the lowest position, respectively. Between the parts, m and 011/, is a portion m, which is a portion of a true are, and which has the effect of causing the member, 19 to pause between the die members 2 and 3 during its downward stroke. The portion m/f is a longer arc which restores the member 19 to its central position toward the end of the cycle ofthe machine and maintains the member 19 in this position during the first part of the next cycle, t'. e., during the time required to expel a completed pail from the machine, and during the time required to lower the next pail to the punching dies.

It will be obvious that a skilful operator would be able to invert a pail and place it between the punching dies of the machine and then at the right instant drop or force the pail down into position to be operated upon by the earing dies. We, however, prefer to equip the machine with positive means for accomplishing the movement of the pail and for expelling or throwing out the completed pail. These means comprise a chuck preferably divided into two parts, 0"0, on opposite sides of the box or bracket, l. These plates carry suitably positioned gages, O, for holding the pail centrally over the dies, Means may be provided for fastening the pail on the chuck plate, but it is usual for the operator to simply place and hold the pail thereon and remove it therefrom when Vfinished and by the cam wheel, L, said yoke having a lug or roller 28, which enters a cam groove, N in said wheel. This groove is laid out in such manner that as the cam wheel is rotated in the direction of the arrow the chuck is lowered to position the pail between the punching dies, 2 12, and is momentarily held in such position, after which the chuck is further lowered and held with the pail before or between the dies, 3 13. Further rotation of the cam, occurring after the dies 3 13 have opened, elevates the. chuck and therebyexpels the completed pail. In the drawings, the parts are shown in the positions which they occupy when the machine is stopped.

As before stated, the ears are fed to the nishing dies automatically. These ears are held in chutes, P, one of which is secured to each of the frame members D. Suitable mechanism is provided whereby one ear at a time is fed to each finishing die at the proper time. To this end, we form the chute in two portions P/ and P, and place the feeding mechanism preferably at the juncture thereof. The portion P/ should be kept practically full of ears while the machine is in operation. It has sufficient pitch to feed the ears forward by gravity and constitutes the magazine, while the portion P constitutes the chute proper and has a greater inclination in order that an ear, when released, will descend with such rapidity as to carry it to the proper' position in a pocket 30 formed in the frame D beneath the inner earing die. The feeding or releasing mechanism referred to comprises a double bell crank lever having two short arms 3l and 32 provided with pins or lugs 33 which project into the path of the ears, and a long arm 34, which projects into the path of the vertically reciprocating chuck plate O. When the chuck plate O is in elevated position the bell crank lever is in the position shown in Fig. lll, but as the chuck plate, O, descends a spring 35 actuates the bell crank lever, throwing the same into the position shown in Fig. 1V which lowers the arm 34 and raises the arm 31, permitting an ear to advance into engagement with the lug 33 on the arm 32. As the chuck plate O rises to the position 'shown in dotted lines in Fig. IV it engages the arm 34 and raises the same. This raises the arm 32 and releases the ear which immediately drops into the pocket 30, the lug on the arm 31 in the mechanism having descended to hold back the other ears in the magazine. Thus it will be seen that at each reciprocation of the chuck plate an ear will be fwd to each of the caring mechanisms. 1n as much as the ear magazines are attached to the frames of the earing mechanisms they will also move therewith when the same are adjusted for different sized pails, hence, as both f eed mechanisms are operated by a single arm 34, some provision must be made for the adjustment of these parts. To this end the arms 31 and 32 are formed upon a sleeve 36 feathered upon the shaft which carries the arm 34. However, instead of providing the one feed mechanism for the two magazines X X we may form them independently, each pair of levers 31 and 32 having its own arm 34 for engagement with the chuck plate, for operating the same.

As previously stated the frames or carriers, D, with their brackets, E, are adjustable with relation to the main shaft, F, land this adjustment is made without vvarying the position of the cam L because` the shaft is held against longitudinal movement, by the bearing shown in dotted lines in Fig. I. At a point outside of the frame the shaft bears a driving pulley G, and the members of the clutch R, whereof S is the pressure arm. The clutch is shown in disengaged condition, in which condition it is held by the stop pin QQ provided on the frame and adapted to be retracted by means of the treadle Q. When the pin is thus retracted the clutch parts which are on the pulley G and the shaft F, respectively, connect the pulley to the shaft and thereby start the machine into action.

The operator having depressed the treadle Q immediately releases the same, thereby restoring the pin Q/ to the path of the lug o1 cam on the movable member of the clutch R; hence, the clutch will be disengaged from the pulley on completing a single revolution. lt will be noted that the pinions, I and I are of the same size; hence, a single revolution of the shaft F, imparts a single revolution to the cam, L, and also to the two shafts, H H, causing single reciprocations of the dies. These being the conditions, it will be readily seen that the operations of all parts of the machine are very easily timed, as the only parts requiring adjustment, for time, are the cams L, 17, 18, and 44.

The operations and functions of the individual members of the machine will be fully understood from the foregoing, and hence, the operation of the machine as a whole will beclear to the reader. Nevertheless, to insure a complete understanding of the invention we will now briefly describe its use and the principal operations performed by it.

Figs. 3 and 4 show that ears are released from the magazines by the rise of the chuck; hence, at the moment that the treadle is depressed to start the machine, the pockets 30 will contain ears 50. A pail held on the chuck O as shown by dotted lines in Fig. 3, will be lowered between the pairs of dies 2 12 by the first downward movement of the chuck. At this instant, the member 19 rises between the die mombers 2 2, projecting them against the inner sides oi the pail in time to meet the outer members l2, which are then forced in by their cams 17. The dies punch the sides of the pail and form flanges of the shape required to fit the kind of ear which is in use. The waste is ejected through the openings 7/ and 7 as before stated. The next step in the operation consists in the retraction of the dies ,12 and 2 and for an instant preceding the movement of the dies 13 13, the wedge member, 19, remains in its mid position. During this time the chuck lowers the pail until the openings therein are directly opposite the dies 3 13. Then the plungers 40 ascend and lift the ears into the spaces between the sides of the pail and the members 3 3. 1n actual operation the descent of the pail and the ascent of the plungers 40, occur at so nearly the same instant that the sides of the pail help to form outer wall guides for the ears, the latter reaching their positions at the moment that the holes in the pail come into alinement with the dies. At such time the wedge member 19 is forcibly drawn down and projects the die members 3 3, thereby driving the ears through the holes in the pail; and instantly thereiastening of the ears therein.

after the clenching, swaging, or seaming dies, 13-13, strike the outer sides of the pail and complete the the dies 13 and 3 are retracted, the wedge member ascending to its mid position, and the plungers Li0 fall into their lower positions ready to receive ears from the magazines. As the latter operations are taking place the cam L, operating through the medium of the yoke 26, elevates the chuck O, expelling the pail and operating the ear feeding mechanism to supply ears to the pockets or plungers, 40. Thereupon the shaft F havingl completed its revolution is stopped by the action o'i the automatic clutch throwing device Q.

It will be readily understood that the function of the `pail as a guide for the ears is preserved when the ears are fed upwardly against the outer sides thereof as before mentioned. It will also be obvious that various modifications not herein specifically mentioned will readily suggest themselves to one skilled in the art and for this reason we do not coniine the invention to the specific structure and sequence of operations herein shown and described.
